The above characteristics are measured at certain condition and it could vary in the different conditions measurement. It is only for reference. These properties can be changed as required by the manufacturer’s improvements without prior notice.
II. FEATURES
Oxidized starch is used in paper industry mainly in surface treatment process in order to:
- Improve the paper surface strength, smoothness and stiffness of the paper.
- Improved printing properties.
- Improve the ability of waterproof paper with adhesive surface quality.
- Improve anti-dusting of paper surface.
- Good compatibility with most chemicals used in surface sizing solution (Size press).
III. APPLICATION FOR SIZEPRESS:
- Batch cooking:
- Dissolve dry starch in cold water with a concentration of 15 - 20 % in the cooking tank equipped with heater and stirrer.
- Heat and stir the powder suspension continuously at room temperature of 90-950C for about
20 minutes to obtain a uniform liquid starch.
- Spray continuously cooking:
- Dissolve dry starch in cold water with a concentration of 6 - 10%.
- Pump the starch suspension through the boiler tube and is heated directly by steam pressure of 2-4 bar
- Maintained the temperature in the cooking tank between 90-950C by adjusting the pressure of steam line.
- It should not be too high temperature in the cooking tank to avoid excessive starch hydrolysis.
- Cooking spray continuously will get lower viscosity than cooking by batch.
